TO ALL WHOM IT MAY CONCERN:

Be it known that I, GEORGEA REHFUSS, of Philadelphia, Pennsylvania,'havc invented certain improvements in Sewing Machines, and I do hereby declare theK following to be a i'ull, clear, and exact description of the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon.

My invention consistsin certain mechanism,`fully described hereafter, for sewing together carpets and other heavy fabrics.

In order to enable others skilled in the art to make and use my invention, I will now proceed to describeits 'construction and operation. On reference to the accompanying drawing, which forms a purtof this specii fication f v A Figure 1 is a sectional elevationtof a sewing machine with my improvements.

Figure 2a sectional plan on the line 1-2, iig. 1, showing part of' the machine; and

Figure 3, a section on the line 3-4, figr2. j

A'is the bed-plate of the machine, to which is secured an arm B, and in the front end of the latter slide the presser-bar C and needle-bar D. To the lower-end of the presser-bar is secured the' ordinary foot a, in which is a slot, a', and to the needle-bar is secured the detachable eyepointed needle b. To the side of the arm B is hung a lever, E, which is jointed to the needle-bar, and is operated by thefmovements of the driving-shaft F in a manner too well known to those skilled in this class of machineryto n ccd particular description. Over a cam, G, secured to the driving-shaft, extends a feed-lever, H, which is hung to a. pin, c, the latter passing. through a slot, and 4to the lever is secured one end of aspiral spring, d, the other end oi' which Vis attached to ,a pin, c, projecting from the base-plate. At the inner ofthe lever are two projections,f and g,'the latter extending beneath lan opening, y, in the work-plate I, and at the upper` side of this projection are two sharppointed pinsz'z'". To the base-plate A is secured what I term a ggidef J, which consists of two plates or jaws, k and k', secured to each other at their rear ends and to the base-plate by a screw, Z, which passes through slots in both plates or jaws and into the base-plate. The upper jawvor plate, k', is elastic, and is so bent that it tends to rise at its rfront end from the plate k and to bear against the under side of a nut, p, which turns on a screw, o, secured to the lower plate. The front ends of thejaws, 7c 1ct, are bent inward so as to form two ribs or flanges,l at, which may be adjusted at any',req11ired distance in respect to each other. by means of the nut p, and through openings in the plate k project rods m m, (secured to the plate 7c,) which prevent any lateral movement of the plate 7c without interfering with the free vertical movement of the same. To a projecting portion of the plate k are secured two pins, w u, which extend through slots in an adjustable plate K, the latter being secured in any position, to which it may be adjustedlby a nut, g, which screws on to the pin u. .At the front end of the plate 7c is au inclined wedge-shaped projection, 1', for a purpose described hereafter. The machine is provided with a shuttle, loop-holder, or other suitable device, by means of which the needle-thread may be secured after 'being passed through the fabric; inasmuch, however, as various devices may be'used'for this purpose, and as the construction and operation of such devices are well-known to those conversant with this class of machinery, it has not been thought necessary to illustrate or particularly describe the same. The c'am G is so constructed that as the shaft F revolves the feed-lever will be raised until the edge of the projection g is flush with the work-plate I, and the pins z' "project into the openings a', then moved forward in the direction of its arrow, and then depressed in the Same manner as feed-levers of the ordinary construction. The strips :z: :v of carpet or other fabric to be sewed together are pla-eed one above the other, the piled surfaces, .whether cut or uncut, being face to face, and are secured between the jaws 71: t by turning -the knntp so that the ribs s t shall press against the fabric near the thick cord or salvage, z, at the edge of the same, this selvage preventing the fabric from being drawn upwards from between the jaws, but not interfering with its free movement between the jaws, toward the needle b. The guide .I is then so adjusted on the base-plate that the needle b when it descends shall penetrate both strips, near the edges of the same, and the plate 7c is movcdforward to the position shown in g. 2, so that the inclined projection, r, shall be between the two strips.

When the machine is pnt in operation, the pins z z', as the lever II is raised, will penetrate both strips, ma', of carpet, and as` the lever moves forward will carry the carp'etiri the same direction to thcextent ofthe nuovement of the lever, after which the needle b will penetrate the strips and carry through the same a thread which is interlocked with the thread of a shuttle or loop-holder in the ordinary manner. As the strips z x are moved toward the needle they will be guided beneath the latter, and their edges will be maintained parallel to each other by the plates k c, while the inclined plate r will fold back the-"pile of both strips near the edges of the same. In sewing carpets it is important that the edges onlyof the strips` should be secured together in order that there may be as little thickness'as possible in the seam, and it is also .fully as important `that the strips should both-be moved towardthe needles at the same speed inorder that the igures in the two may coincide with each other. In the above-described devices the plates It k maintain ,the edges of the two strips parallel and guide them' with such nicety beneath the needle that `the latteil will invariably penetrate the fabric at a point just back of the selvage, while, as the'pins c' penetrate both strips, it will be apparent thatnot only will they both be fed forward at the same speed but the pinsprevent the relative positions of the strips from being altered after they leave the guide. By the use also of the plate 7c and its projection for turning in the pile, the latter is folded back so that the edges of the strips may beibrought closely together. The form of the plates or jaws c k may be altered without departingvfrom the main features of my invention, and in some instances, where the pinsz'z' would maintain the edges of the two strips-of fabric parallel with each other, the lguide, may be dispensed with. In this case, however, a plain hemming guide should be secured to the base-plate to guide the fabric Ato the needle. The plate K may beused without the guide'J by bringing it nearer to the' needle and presser-foot than shown in the drawing. By the use of a slotted presser-foot the fabric may be held firmly down on to the feed, while the points of the pins 'iz' are prevented from being injured by being brought into contact with the foot. v i

I claim as my invention,a.nd desire to secureby Letters Patentv 1. The adjustable jaws- 7: t, with their ribs or iianges s t, constructed and adapted for attachment to a sewing machine, substantially as and for the purpose described.

2. The pins t' i applied to a feeding device, and combined with a slotted presser-foot into the slot in which the pins project when-above the work-plate, substantially asand for the purpose described.

' 3. The adjustable plate K, with its inclined projection r, qonstructed and adapted for attachment to a sewing machine, substantially ,as and for, the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
